A callus (tyloma) is a thickening of the skin that occurs in response to excessive, repeated shear or friction forces, commonly due to constant rubbing of the skin. Calluses are similar to corns, but calluses occur when abnormal forces are exerted over a larger area. Certain deformities of the feet, such as crookedness of the toes, may predispose to the development of calluses. Calluses may cause pain, typically a burning sensation. Excessive weight bearing and certain types of shoes are often contributing factors.
An abscess is a localized collection of pus that generally develops in response to infection. An abscess is typically painful, and it appears as a swollen area that is warm to the touch. The skin surrounding an abscess typically appears pink or red.
Fever of Unknown Origin
Fever is a protective response to infection and injury. An elevated temperature enhances the body's innate defense mechanisms by making conditions less favorable for infectious microorganisms to thrive. An elevated body temperature, for example, decreases the levels of iron in the bloodstream, thus inhibiting the growth of some microorganisms. People with fevers also tend to eat less and rely more on fat and protein sources for energy, which decreases the blood glucose levels upon which bacteria normally thrive. In addition, there are some microorganisms that are heat-sensitive, and do not grow well at elevated body temperatures.
When antigens (foreign substances that invade the body) are detected, several types of cells work together to recognize them and respond. ...
